World Cup festivities include all-star concert

ABC to air event with John Legend, Alicia Keys, BEP Friday

NEW YORK -- John Legend is like a lot of Americans -- he's not an avid soccer fan, but when the World Cup comes around, he gets into it.

Legend says "it's a sport that's easy to follow, and when there's the extra kind of excitement of such a big event, it's something that I definitely can watch."

Legend has even more reason to be excited about this World Cup, which begins Friday in South Africa: He is one of the performers at an all-star concert that kicks off festivities for the massive event. Other acts include Alicia Keys and the Black Eyed Peas.
